- The Hypoglossal nerve (CN XII) provides motor supply to the muscles of the tongue. Observe the tongue for any signs of wasting or fasciculations. Ask the patient to stick their tongue out. If the tongue deviates to either side, it suggests a weakening of the muscles on that side.

- Shampoo plus conditioner products help to solve this problem by combining the surfactants found in shampoos with the moisturizers and nutrients found in conditioners into single formulas. As a result, you simply lather and rinse one time to get the benefits of both products.Dry shampoos are special products that absorb oil and dirt from the scalp and strands but do not require rinsing. These formulas are usually powder-based and may be sprayed onto the hair or shaken onto the scalp.ry shampoos are special products that absorb oil and dirt from the scalp and strands but do not require rinsing.

- Lingual nerve. The lingual nerve is located near the sides of the tongue (specifically below the lateral pterygoid muscle), and is responsible for its senses of taste and touch. The lingual nerve provides senses to the tongue's front two-thirds, as well as to the underside that surrounds it.It branches off the mandibular nerve and twists around the submandibular duct to reach the tongue.he lingual nerve provides senses to the tongue's front two-thirds, as well as to the underside that surrounds it.

- It is also possible to test the gag reflex by touching the pharynx with a tongue depressor. Most people omit this unless there is evidence of a local lesion. It is unpleasant and around 20% of normal people have a minimal or absent response. Isolated lesions of the IX nerve are very rare.

Medical Definition of Nerve, vagus The vagus nerve also brings sensory information back to the brain from the ear, tongue, pharynx, and larynx. The vagus nerve is the tenth cranial nerve. It originates in the medulla oblongata, a part of the brain stem, and wanders all the way down from the brainstem to the colon.

Glossopharyngeal neuralgia (throat pain) Neuralgia is severe pain caused by injury or damage to a nerve. The glossopharyngeal nerve is the ninth (IX) cranial nerve, which arises from the brainstem inside the skull. It supplies sensation to the back of the throat and tongue and portions of the ear (Fig.1).igure 1. The glossopharyngeal nerve (9th cranial nerve) is related to the back of the tongue and throat. It has branches to the ear, tonsil, and carotid body. Glossopharyngeal pain can be similar to trigeminal neuralgia – and misdiagnosed.

The Cranial Nerves and Their Functions The Facial Nerve The facial nerve is complicated. Not only does it control most muscles of the face; this nerve also transmits taste signals from the front of the tongue, conveys parasympathetic fibers that make the eyes tear and mouth salivate, and is responsible for a little bit of sensation around the ear.

Medical Definition of Nerve, vagus And the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx. The term vagus (Latin for wandering) is apt because the vagus nerve wanders all the way down from the brainstem to the colon, a long wandering trek. Complete interruption of the vagus nerve causes a characteristic syndrome.The back part of the palate (the soft palate) droops on that side.The capacity to gag (the gag reflex) is also lost on that side.nd the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx.

From tongue to brainstem From tongue to brainstem. As diagrammed in this image, the three taste nerves and the trigeminal nerve bring their messages to the brainstem, where they combine their signals in areas that are involved with arousal (for example from sleep), and are - according to Antonio Damasio in The Feeling of What Happens - the locus of our sense of core self. Smell and the brain

Tongue Anatomy General sensation of the anterior two thirds of the tongue is supplied by the lingual nerve, a terminal branch of the third division of the trigeminal nerve (V3). Taste sensation for this portion of the tongue is carried by the chorda tympani branch of the facial nerve.

Genioglossus The genioglossus is one of the paired extrinsic muscles of the tongue. The genioglossus is the major muscle responsible for protruding (or sticking out) the tongue.

- Symptoms & Signs. Numbness or tingling (pins and needles) sensations in the tongue, medically known as paresthesia of the tongue, most commonly occur due to damage to the nervous system. The medical term for the absence of sensation is anesthesia.

The Glossopharyngeal Nerve (CN IX) The glossopharyngeal nerve supplies sensory innervation to the oropharynx, and thus carries the afferent information for the gag reflex. When a foreign object touches the back of the mouth, this stimulates CNIX, beginning the reflex. The efferent nerve in this process is the vagus nerve, CNX.ig 1.2 – Path of the parasympathetic fibres to the parotid gland. The glossopharyngeal nerve provides parasympathetic innervation to the parotid gland. These fibres originate in the inferior salivatory nucleus of CN IX. These fibres travel with the tympanic nerve to the middle ear.

- Feedback from motor movements, especially tongue movements which are mediated by the hypoglossal nerve, also help to trigger the swallow. Input from both the cerebral cortex and the cerebellum is responsible for the coordination and timing of the motor movements involved in swallowing. Mnemonic for the Cranial Nerves.

Hypoglossal nerve The path of the nerve starts in the hypoglossal nucleus of the brainstem, which is located near the midline of the medulla oblongata, and then travels between the carotid artery and jugular vein to end up on the underside of the tongue.If there are problems with the hypoglossal nerve, the tongue may become paralyzed.To test the nerve’s function, a patient would be asked to stick out their tongue. If paralysis were present, the tongue would point in the direction of the affected side.he hypoglossal nerve is the twelfth cranial nerve and controls movements of the tongue.

The Hypoglossal Nerve (CN XII) The hypoglossal nerve is the twelfth paired cranial nerve. Its name is derived from ancient greek, ‘ hypo ‘ meaning under, and ‘ glossal ‘ meaning tongue.The nerve has a purely somatic motor function, innervating the majority of the muscles of the tongue.ig 1.0 – The extracranial anatomical course of the hypoglossal nerve. The hypoglossal nerve arises from the hypoglossal nucleus in the medulla oblongata of the brain. It then passes laterally across the posterior cranial fossa, within the subarachnoid space. The nerve exits the cranium via the hypoglossal canal.

- Chapter 7 - Lower cranial nerve function. The lower cranial nerves are involved in pharyngeal and laryngeal function as well as in movements of the neck and tongue. Damage usually manifests as problems with speech and swallowing. These nerves arise from the medulla and, in the case of the accessory nerve (CN XI), the spinal cord.

How Your Tongue Works The tongue and its muscles are laterally symmetrical: a median septum divides the organ into two halves. The tongue is made up of two types of muscles: extrinsic and intrinsic. Extrinsic muscles originate from elsewhere in the body and attach to the tongue. They connect with surrounding bones and help the organ move up and down, from side to side and in and out.

What is the Glossopharyngeal Nerve? The glossopharyngeal nerve allows perception of taste on the hindmost portion of the tongue. Cranial nerves are vital nerves that arise from the brain that help the brain control muscles, process the five senses, and control glands in the body. Symptoms of glossopharyngeal neuralgia may include ear pain.

Chapter 5: Facial sensations & movements The motor portion of. this nerve supplies the muscles of the face and scalp: buccinator, platysma and so on, along with. motor control to the submandibular, sublingual and lacrimal glands. The sensory portion of this. nerve carries sensory information for taste from the anterior 2/3 of the tongue and the palate. Lesions of the facial nerve cause facial paralysis that is usually unilateral. There is also a loss of. taste sensation in the anterior 2/3 of the tongue and decreased salivation.

What is the Gag Reflex? The gag reflex, also known as the pharyngeal reflex or laryngeal spasm, is a contraction of the back of the throat triggered by an object touching the roof of your mouth, the back of your tongue, the area around your tonsils, or the back of your throat.
